Path Selection Methods with Multiple Impairment Constraints Based on Flooding Approach in Transparent Optical Networks
Set out from the evolution of optical network to all optical transparent frame,this paper analyzes the major physical impairments in transparent optical network and their constraints on route selection. A novel impairment-aware routing and wavelength assignment algorithm based on flooding path information message is proposed.
